Fruiting season  May to June (Chacko et al.,2002).

Fruits  Fruit globose, 1cm across, scales in 24 rows (Chacko et al.,2002).
Fruit type 
Seeds  1 seeded.
Seed length  1.2 cm (Chacko et al., 2002).
Seed width  1.0 cm (Chacko et al., 2002).
Seed thickness 
Seed weight  6,500 to 7,500 seeds/kg (Chacko et al., 2002).
Seed dispersal 
Seed Collection  Fruits, when they attain golden yellow colour are collected from the plant by slowly pulling down the fruit bearing branch (Chacko et al., 2002).
Transportation of seeds  Fruits are transported to the nursery immediately after collection. It is better to carry them as bunches in moist gunny bags (Chacko et al.,2002).
Seed processing  The fruits are de-pulped after soaking in water for 24 to 48 hrs and removing the fleshy disintegrated pericarp by rubbing between the palms. The seeds are then cleaned by washing in water several times and then stored in moist sawdust so that seeds do not dry up (Chacko et al.,2002).
Seed storage  Probably recalcitrant. Seed storage is not recommended; however, the seeds can be stored in moist sawdust for about one month without loss of viability (Chacko et al., 2002).
Viability period  Seeds retain viability up to a month (Chacko et al., 2002).
Seed emptiness  No information (Chacko et al., 2002).
Seed pre treatment  No pretreatment other than de-pulping (Chacko et al., 2002).
Germination type  Adjacent ligular (Chacko et al.,2002).
Germination percentage  85 to 95 (Chacko et al.,2002).
Germination period  30 to 120 days (Chacko et al.,2002).
Nursery technique  Seeds are sown in raised nursery beds filled with soil-sand mixture (3:1). After sowing, seeds are covered with a thin layer of sawdust. Partial shade is necessary. Seedlings are potted in polythene bags during the 4-leaved stage when the seedlings attain around 3-4 cm height, ie., usually for this species it takes 1 to 1 1/2 months, after germination (Chacko et al., 2002).
Method of propagation 
Vegetative propagation 
Pests  No information (Chacko et al.,2002).
Diseases  No information (Chacko et al.,2002).
Medicinal properties  The leaves of this cane species are medicinal, used in the treatment of biliousness, worms and ear complaints.
Uses  It produces good quality small diameter cane used for handicrafts and furniture (Chacko et al., 2002).
